.SHORT TERM...
(Tonight through Monday night)
Issued at 1259 PM CDT Sat Oct 4 2025
A weak surface low is noted over the north central Gulf along an
old stalled frontal boundary extending across the Gulf and through
the Florida Straights. This surface low is non-tropical and has a
zero percent chance of developing according to NHC, as strong
wind shear will be found over the northern Gulf and the low
remains more like a surface wave as it moves to the Texas coast on
Monday.
Elevated easterly flow between the low and a high over the Mid-
Atlantic will gradually increase moisture across the forecast area
through Sunday and Monday. With the increase in moisture, an upper
level disturbance retrograding with the surface low, and low level
convergence with a coastal trough/old frontal boundary, showers
and a few thunderstorms are expected to increase during the day on
Sunday and continue into Monday.
The highest moisture will be over lower Acadiana, and this is
where the higher pops will be during this period along with the
potential for higher rainfall amounts, which will be much needed
with the recent increase in drought conditions.
With the elevated easterly winds and Ekman spiral affects, tides
will run about a foot to a foot and a half above normal that will
bring water piling along the coast of southeast Texas and
southwest Louisiana into Sunday that may bring about some
nuisance minor coastal flooding.
